How do coalition governments affect the risk of civil war onset in ethnically divided societies? Existing research argues that power-sharing coalitions decrease the risk of civil war because they redress grievances. Building on a formal model of coalition formation, we predict that ethnic elites are most likely to form oversized rather than minimum-winning coalitions in anticipation of future challenges to the regime. Put differently, we expect most power-sharing to occur where the risk of regime-threatening civil war is highest.

Barbara Walter's application of reputation theory to self-determination movements has advanced our understanding of why many separatist movements result in armed conflict. Walter has shown that governments of multi-ethnic societies often respond to territorial disputes with violence to deter similar future demands by other ethnic groups. When governments grant territorial accommodation to one ethnic group, they encourage other ethnic groups to seek similar concessions. However, a number of recent empirical studies casts doubt on the validity of Walter's argument. We address recent challenges to the efficacy of reputation building in the context of territorial conflicts by delineating the precise scope conditions of reputation theory. First, we argue that only concessions granted after fighting should trigger additional conflict onsets. Second, the demonstration effects should particularly apply to groups with grievances against the state. We then test the observable implications of our conditional argument for political power-sharing concessions. Using a global sample of ethnic groups in 120 states between 1946 and 2013, we find support for our arguments. Our theoretical framework enables us to identify the conditions under which different types of governmental concessions are likely to trigger future conflicts, and thus has important implications for conflict resolution.

The article of record as published may be found at http://dx.doi.org/10.1093/isq/sqw031 ; Why do most civil wars occur in a relatively small number of countries? We answer this question by analyzing how civil wars diffuse in multiethnic states. Our theory outlines two motivation and two opportunity mechanisms that trigger additional ethnic rebellions in the same state. First, ongoing civil wars motivate members of other ethnic groups to mobilize in reaction to the negative externalities of nearby conflict. Second, ethnic groups emulate nearby rebel groups as a means of addressing preexisting grievances. Third, fighting multiple civil wars drains state capacity, opening the door for additional challengers to rebel against the government. Finally, long-lasting civil wars signal that the state is unable to defeat active rebels, thus creating incentives for new challengers to take up arms. We test our mechanisms in all multiethnic states with a history of armed conflict between 1946 and 2006. Using Geographic Information Systems, we construct overlap and minimum distance measures between ethnic groups' settlement patterns and conflict zones. Our statistical analysis indicates that new ethnic civil war onsets are more likely in the vicinity of ongoing armed conflicts. Ethnic civil wars also diffuse as governments face an increasing number of rebels and longer rebellions.

Social scientists in general and conflict researchers in particular increasingly combine multiple datasets to study ethnic politics and conflict in Africa. We facilitate these efforts by systematically linking over 8,100 ethnic categories from 11 databases, including surveys, geographic data, and expert-coded lists. Exploiting the linguistic tree from the Ethnologue database, we propose a systematic solution to the grouping problem of ethnicity. An analysis of political exclusion, mistrust of state leaders, and ethnic grievances highlights different ways of linking ethnic categories from multiple datasets. The LEDA open-source software package allows researchers to link ethnic groups from any database with explicit rules and to add their own data on ethnic groups.
